Fabrication of novel Ag4Bi2O5-x towards excellent photocatalytic oxidation of gaseous toluene under visible light irradiation

Applications of bismuth-based nanoparticles for the removal of pollutants in wastewater: a review

“…Compared to other methods, the preparation process using ball milling is relatively straightforward and can be carried out at room temperature. Chen et al 117 utilized a simple ball milling approach to fabricate a novel oxide incorporating both Bi and Ag. Specifically, a certain proportion of raw materials was In contrast to more complex methods, Gong et al 118 synthesized a novel peroxide nanomaterial composed of AgBiO 3 NPs through a straightforward ion-exchange approach.…”

“…Compared to other methods, the preparation process using ball milling is relatively straightforward and can be carried out at room temperature. Chen et al 117 utilized a simple ball milling approach to fabricate a novel oxide incorporating both Bi and Ag. Specifically, a certain proportion of raw materials was introduced into a ball mill, and after milling at a speed of 450 r min −1 for 1 hour, yielding the black solid Ag 4 Bi 2 O 5− x sample.…”

“…For instance, the recombination of photogenerated e − and h + on the catalyst surface may occur, leading to a reduction efficiency of photocatalytic reactions. 117,132 Additionally, the optical absorption range of Bi-based NPs is mainly confined to the visible and ultraviolet regions, limiting the utility in photocatalytic applications. Lastly, the limited number and stability of active sites constrain the capture and stable involvement of photogenerated e − and h + in reactions.…”
